High-Resolution Measurements of Mercury’s Surface Composition with the MESSENGER X-Ray Spectrometer
We present updates to major-element maps of Mercury using low-orbit observations from MESSENGER’s X-Ray Spectrometer.

Volatile Abundances in Apollo 12 Red Volcanic Glass
A12 red volcanic glass, together with other glass groups, show shifts in S/Dy at constant F/Nd that may be a signature of degassing of the lunar magma ocean.

Large Variations in the Volatile Content of Olivine-Hosted Melt Inclusions from Lunar Magmas
New volatile analyses of lunar melt inclusions from A17 orange glass extend the range to higher Cl, F, and S contents, and first document their C contents

Alan Boss
Tuesday, 17 March 2015 @ 6 p.m., Poster Session I: Isotope Geochemistry: Origins of Isotope Heterogeneities
Supernova Shock Triggering and Radioisotope Injection into the Presolar Cloud: Effects of Rotational Axis Orientation
Three-dimensional models of presolar clouds rotating perpendicular to shock front direction are consistent with the supernova triggering and radioisotope injection hypothesis.

Correlation Between Raman Peak Shifts and Isotopic Compositions of Sub-Micron Presolar SiC Grains
We report a positive correlation between the SiC Raman peak positions and the 12C/13C ratios for 11 submicrometer to micrometer-sized mainstream presolar 3C-SiC grains.

Are Radicals the Carriers of D in IOM?
We do not observe the expected correlations between D/H and radical concentration, determined by EPR, if exchange with H3 + caused the D-enrichments in IOM.

Organic Matter in the Unique Carbonaceous Chondrite Miller Range 07687: A Coordinated In Situ NanoSIMS, FIB-TEM, and XANES Study
Coordinated in situ analyses of organic matter (OM) in MIL 07687 indicate it lacks nanoglobules, unlike OM previously observed in other chondrite groups.
Thursday, 19 March 2015 @ 6 p.m., Poster Session II: Chondrites: Making and Breaking Parent Bodies
Miller Range 090657: A Very Pristine Renazzo-Like (CR) Carbonaceous Chondrite
We report isotopic, chemical, and mineralogical data that suggest Miller Range 090657 is one of the most pristine CR chondrites analyzed to date.
